Toyota Raum Engine ReplacementCompare Prices & Save

Key points

• • Z10 models (1997-2003) use the 5E-FE engine producing 91-94 PS
• • Z20 models (2003-2011) use the 1NZ-FE VVT-i engine producing 105-109 PS
• • All Raum models are automatic only; manual gearboxes were never offered
• • 4WD variants produce 4-5 PS less than equivalent 2WD models due to drivetrain losses

Key points

• • 1NZ-FE engine is shared across Yaris XP9, Corolla E120/E130, RAV4 XA20 and Raum Z20
• • Ensure donor vehicle matches your Raum's drivetrain (2WD vs 4WD) for correct ECU mapping
• • First-generation Raum Z10 (5E-FE) has more limited cross-compatibility options
• • Always verify engine number location and chassis code before purchasing a donor unit

Key points

• • Most 1NZ-FE units reach 150,000+ miles with regular servicing and timely coil replacement
• • Ignition coils typically fail between 60k-100k miles; replacing all four preventatively is recommended
• • VVT-i rattle on cold start indicates timing chain tensioner wear requiring attention before catastrophic failure
• • Water pump and oxygen sensor failures are common age-related issues on imports over 100k miles

Key points

• • 1NZ-FE rebuilt engines: £950-£2,800 supply-only; £1,400-£3,650 with fitting
• • 5E-FE rebuilt engines: £850-£2,200 supply-only; £1,300-£3,050 with fitting
• • Used engines from UK breakers: £650-£1,800; verify compression before purchase
• • JDM direct imports may cost more but offer lower-mileage options for Z20 models

Key points

• • 1NZ-FE produces 105-109 PS vs 5E-FE's 91-94 PS; better fuel efficiency and emissions
• • 1NZ-FE uses coil-on-plug ignition (more reliable); 5E-FE uses distributor (prone to failure)
• • 1NZ-FE is widely available from UK Yaris/Corolla donors; 5E-FE sourcing is more limited
• • Both engines use the same 1.5L displacement and 4-speed Super ECT automatic transmission

Key points

• • Replace ignition coils preventatively at 60k-80k miles to avoid misfire-related damage
• • Address VVT-i rattle promptly to prevent timing chain guide wear and potential engine damage
• • Use recommended 5W-30 synthetic oil and follow 6-month/6,000-mile service intervals for imports
• • Water pump replacement at 100k miles alongside timing service extends overall engine life significantly

Key points

• • Our network includes workshops familiar with Raum chassis codes NCZ20, NCZ25, EXZ10, EXZ15
• • Supply & fit quotes include removal, installation, fluids, ECU adaptation and road testing
• • Specialists can source engines from UK breakers or arrange JDM direct imports based on your budget
• • All fitted engines include minimum 12-month unlimited mileage warranty for peace of mind

Key points

• • Warranty terms vary slightly by supplier; always confirm exact coverage before purchase
• • Used engines typically carry shorter warranties (3-6 months); rebuilt units offer 12+ months
• • Warranty covers manufacturing defects and premature failure, not misuse or poor maintenance
• • Keep all service records and installation receipts to validate warranty claims if needed

Key points

• • Compare replacement cost (£1,400-£3,650 fitted) against your Raum's current market value
• • Consider sentimental value, low mileage chassis, or recent major investments (suspension, bodywork)
• • A rebuilt 1NZ-FE with upgraded components may offer better long-term value than repeated repairs
• • If the Raum has rust, accident damage or high-mileage transmission issues, scrapping may be more economical

Key points

• • Faulty ignition coils cause misfires that significantly increase fuel consumption and emissions
• • Oxygen sensor failure leads to incorrect air-fuel mixture calculations by the ECU
• • Carbon buildup on intake valves and throttle body restricts airflow, reducing efficiency
• • First-generation 5E-FE engines are more prone to high consumption complaints than updated 1NZ-FE units
